Benchmarks: Atto Disk Benchmark
The Extreme II 240GB maxed out at 550MB/s, which is roughly in line with the Samsung SSD 840 Pro 512GB, SSD 830 512GB and OCZ Vector 256GB. SanDisk's drive performed impressively in the 1K, 2K, 8K and 32K tests.
Again, we see that the SanDisk Extreme II 240GB is a beast when working with 1K, 2K and 8K data in Atto Disk Benchmark's write test. It's not until we reach the 32K and 128K sets that the other SSDs are able to close in.
